Abstract

The utility model discloses a safety bar chain lock detains relates to safety bar manufacturing technical field, include and establish a plurality of snap rings on safety bar the intra -annular of snap ring is equipped with the mousing -hook who is used for carrying on the hasp to the chain, the snap ring is including fixing last last horizontal pole and the sheer pole of safety bar, go up the horizontal pole with it has the arc pole to join between the sheer pole. Compared with the prior art, the utility model discloses during snap ring on the chain passes safety bar, directly detains the chain link on mousing -hook after taut, can flare -out the chain between per two safety bar and tighten, prevent effectively that the chain from relaxing, play safety protection and act on. Because the chain link can directly detain on mousing -hook, do not need the other use connection of breaking out for a short time, chain easy dismounting is swift, draws the work efficiency who establishes the chain obviously to improve, save and purchase the expense of breaking out for a short time, reduction in production cost.

Description

Safety pole chain latches

Technical field

This utility model is related to safety pole manufacturing technology field, especially a kind of quickly fixing chain on safety pole Lock.

Background technology

In modern ships building course, body section completes to transport, stands up, lift after, building berth or segmentation on follow-up Before entering the work of sand room, set work in order to safety must first complete drawing of the chain of security protection, chain is by the safety being separated by about 2 meters Bar, as supporting, is installed with two snap rings on safety pole, and chain passes through the snap ring on safety pole to draw and sets, so first installing After fixing safety pole, then draw and set chain.Because chain has at least 30 meters long, and chain cannot be locked through snap ring, unavoidable meeting Lax phenomenon occurs, does not have the purpose of security protection, can also leave potential safety hazard；It is thus desirable to after tension chain, passing through Chain is buckled and fixes on snap ring by little shackle, and such way work efficiency is relatively low；And all need in addition to buy little unloading every year Button, little unload to be buckled in life-time service get rusty easily so that partly being difficult to get loose after little shackle corrosion, turnover rate is high, increases and produces Cost.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of safety pole chain lock, passes through card to solve chain Ring could not be locked and lax, need by little shackle buckle chain on snap ring problem is occurred.

In order to solve the above problems, the technical solution adopted in the utility model is: this safety pole chain lock, including setting Multiple snap rings on safety pole, are provided with the mousing-hook for being latched to chain in the ring of described snap ring.

In above-mentioned safety pole chain lock technical scheme, more specifically technical scheme is it may also is that described snap ring is included admittedly It is scheduled on the cross tube on described safety pole and sheer pole, between described cross tube and described sheer pole, be linked with bow.

Further, described mousing-hook is provided with the arc hook towards described safety pole for the opening, under described arc hook End is linked with the connecting rod of rectangular setting, and described connecting rod is connected with described safety pole.

Further, described mousing-hook is s shape hook, and described s shape hook is connected with described safety pole.

Due to employing technique scheme, this utility model compared with prior art has the advantages that

1st, this utility model is provided with the mousing-hook for being latched to chain in the ring of snap ring, and chain passes through safety pole On snap ring when, after tension, chain link is directly buckled in mousing-hook, the chain between each two safety pole can be stretched Tighten, effectively prevent chain from relaxing, play safety protection function.Because chain link can directly be buckled in mousing-hook it is not necessary to make Use little shackle, disassembling chains are convenient and swift, draw the high working efficiency setting chain；Save the expense buying little shackle, reduce and produce Cost.

2nd, mousing-hook is provided with the arc hook towards safety pole for the opening, and arc hook is fixed directly through chain link, has Effect prevents chain from slipping.

3rd, mousing-hook is s shape hook, and s shape hook is connected with safety pole, buckles chain and is more convenient, and effectively prevents chain from slipping.

Brief description

Fig. 2 is the partial enlarged drawing at the i of Fig. 1.

Fig. 3 is the structural representation of this utility model embodiment 2.

Fig. 4 is the partial enlarged drawing at the place of Fig. 3.

Specific embodiment

The utility model is described in further detail for embodiment below in conjunction with the accompanying drawings:

Embodiment 1

A kind of safety pole chain lock as shown in Figure 1 and Figure 2, including two snap rings 2 being fixed on safety pole 1, in card The ring of ring 2 is built with the mousing-hook 3 for being latched to chain；Snap ring 2 includes the cross tube 2-1 being welded on safety pole 1 With sheer pole 2-3, between cross tube 2-1 and sheer pole 2-3, it is linked with bow 2-2；Mousing-hook 3 has opening towards safety pole 1 arc hook, the lower end of arc hook is linked with the connecting rod of rectangular setting, and connecting rod side is welded with safety pole 1, even The lower end of extension bar is welded with sheer pole 2-3；Mousing-hook 3 adopts round steel bending and molding.

Chain link, when chain passes through the snap ring 2 on safety pole 1, is directly buckled in mousing-hook 3 after tension by this utility model, Chain between each two safety pole 1 can be carried out stretching tightening, effectively prevent chain from relaxing, play safety protection function. Connect it is not necessary to additionally use little shackle because chain link can directly be buckled in mousing-hook 3, disassembling chains are convenient and swift, draw and set The high working efficiency of chain；Save the expense buying little shackle, reduce production cost.

Embodiment 2

A kind of safety pole chain lock as shown in Figure 3, Figure 4, including two snap rings 2 being fixed on safety pole 1, in card The ring of ring 2 is built with the mousing-hook 3 for being latched to chain；Snap ring 2 includes the cross tube 2-1 being welded on safety pole 1 With sheer pole 2-3, between cross tube 2-1 and sheer pole 2-3, it is linked with bow 2-2；Mousing-hook 3 is bent into using round steel S shape hook, the lower end of s shape hook and safety pole 1 weld.

The mousing-hook 3 of this enforcement adopts s shape hook, and the top of s shape hook is guide part, makes chain link pass through guiding and smoothly buckles into, s The bottom of shape hook is anti-delinking part, effectively prevents chain releasing；And increase the distance between anti-tripping 3 and snap ring 2, make difference The chain link of big gimmal can buckle into easily anti-tripping, and chain easier through snap ring 2, buckle in mousing-hook 3, chain Bar draws and sets speed faster, and safety is also preferably ensured.
